2. Assume we have three bOxes, each of which has ten numbered balls as follows: • Box 1 has 10 balls numbered from 1 to 10. • Box 2 has 10 balls numbered from 11 to 20. • Box 3 has 10 balls numbered from 21 to 30. Suppose you draw one ball from each box at random. What is the probability that the sum of the three numbers is an even number.
